Acer Introduces Aspire S5 — World's Thinnest Ultrabook

Acer kicked off CES 2012 today with the introduction of the Aspire S5, billed as the world's thinnest ultrabook. With a 13.3-inch LCD display, the computer measures 15 mm at its biggest point and weighs less than 3 lbs.

Using the same Instant On technology as the Timeline, the S5 boots to full functionality in 1.5 seconds and boasts a battery life of "several weeks," according to a statement by Acer. The included Always Connect feature wakes the S5 from sleep mode via a separate device like a tablet or smartphone. AcerCloud, Acer's multiplatform compatible response to customer cloud storage, will come pre-installed on the S5.

Despite its size, the S5 does include external ports, hidden within what Acer calls a MagicFlip I/o port panel. A touch of the MagicFlip key reveals an HDMI, USB 3.0, and 20 Gbps Thunderbolt port. You heard it — Thunderbolt. The brushed black metallic cover is made of magnesium-aluminum alloy. An Intel CoreTM processor, SSD storage, and Dolby Home Theater v4 round out the S5's inner specs.

Look for the S5 to ship in the second quarter of 2012, when pricing will also be announced. Check out a first look at the new ultrabook in the gallery!
